Answer 1

Hello there!

Surface Area = 4pir^2

First, we need to find our radius, since we have our diameter all we need to do is divide it by 2. That means, 10 divided by 2 equals 5.

Our radius is 5.

Now, we can plug it into the formula.

4(3.14)(5^2)

4(3.14)(25)

4(78.5)

4(78.5) = 314

Now, convert into pi.

314 = 100pi or 100Π
